Better positioning of temperature logger: In the product packaging or on the pallet
Better positioning of temperature logger: In the product packaging or on the pallet
Often our customers, Ask Us, "Why monitor the ambient air temperature of the trailer container and not the product;"Or in other words, why placing a TempTale® recorder on the outer surface of a pallet is preferable rather than inside a box;
The answer includes a combination of factors, Strongly affecting the thermal behavior of the product during transport:
- The loading temperature is often not uniform between the pallets or even between the boxes in the same pallet.
- When the trailer air temperature changes, Significant temperature variation is observed between the most exposed positions (such as the surfaces and corners of the boxes and pallets) and Central boxes and pallets. For the product loaded at the correct temperature, The risks to food quality and safety tend to be in areas that are exposed. The placement of a record or a catheter at the core of a product, box or pallet often covers temperature changes occurring in more exposed locations, Providing a misleading picture of what is actually happening with the product as a whole.
- The position of the product in the box and on the pallet.
- The position of the box inside the pallet and the position of the pallet inside the trailer.
Avoidance of Inadequate Refrigeration or Freezing
Food professionals are trained to carefully examine the temperature of the product or core to avoid inadequate or incomplete cooling or freezing. It is important to ensure that the correct temperature of the product has been achieved & #8216; throughout the transport, Before loading a trailer (See. Keep the cold chain in four easy steps). However, Focusing only on the temperature of the product during transport, It will result in temperature problems and missing opportunities to improve the process.
Air Temperature is Important
Product temperature is important. But measuring one or a very limited number of product niches will ultimately provide confusion about what's going on. Measuring the air temperature of the trailer shows us more than the temperature of a particular product box at this load. Air temperature is the primary factor that affects the temperature of the product. The measurement of air, understands what causes product temperature changes and better reflects on the overall temperature performance of the load. Examples of events that are easier to detect and understand when measuring air temperature are extended door openings, Malfunctions of the refrigeration unit, incorrect settings of the refrigeration unit, etc.
Correct temperature control
A temperature probe or logger inside a box that shows good product temperature does not necessarily mean that the rest of the load is in order. Understanding how product temperatures change in response to changes in air temperature will help managers become more comfortable using air temperature information effectively. People are often surprised to learn that in many cases the temperature of the product closely follows the temperature of the air circulating in the trailer.
Air temperature is the controlling factor that affects product temperature, which means that the air temperature information of the trailer is more drastic than the temperature of the product. If the loading temperature is good, and air temperature and circulation are properly maintained, The result for the whole load will be good. When measuring trailer air temperature, we make sure to take into account reasonable door openings and defrost cycles when setting the alarm limits of the recorder and interpreting the graphs.
